7 Claims.

This invention relates generally to weighing scales and moreparticularly to scales having a low and comparatively high capacity orweighing range.

One of the principle objects of this invention is the provision of adial or chart graduated to indicate the amount of material required tofill various sizes of containers.

Another object of this invention is the provi- Sion of a dial or chartgraduated to indicate the amount of material or substances required tomake Various quantities of a mixture.

A still further object is the provision of a scoop for scooping upmaterials and automatic means for indicating the weight or quantity ofmaterial in the scoop.

Various scales have been devised for indicating the weight of differentsubstances for a denite receipt or formula, in some a different chartmust be used for each separate receipt, in others the differentingredients are assigned certain numbers or symbols having no relationto the weight or quantity of material. In my invention I provide adevice for indicating the amount of a substance required such as coffeefor making a certain number of cupfuls of a mixture, also for makingpastries I provide a dial showing quantity of various materials orsubstances in cupfuls and teaspoonfuls. With this dial it is possible toweigh the quantity of Various substances in a receipt using the sameterms that are now in common use.

These and other objects and advantages will be apparent from thefollowing detailed description, reference being had to the accompanyingdrawing in which:

Fig. 1 is a front elevational View of a scale embodying my invention.

Fig. 2 is a plan view of the mechanism shown in Fig. 1 and shows in partthe arrangement of the several rows of graduations on the dial.

Fig. 3 is a detail view in a straight plane of the dial or chart showingthe arrangement of graduations for various substances.

Fig. 4 is an end elevation or" the indicating finger and guard in Fig.1.

Fig. 5 is a detailed view of a support.

In the drawing, 6 represents a vertical channel shaped member, which hassecured to its lower end a handle 1. This handle 1 may be replaced by ahorizontal support 8, for supporting the scale in an upright position.Between the edges of the vertical channel shaped member 5, one end ofeach of the levers 9 and I0 is pivoted in suitable bearings such as 9and IU shown in ,indicator or linger 24, better shown one edge of thechannel 6. The other end of each lever is pivoted between the edges ofthe vertical channel shaped load member II in similar bearing 9 and Iiishown in the front edge of the channel II, Fig. l. This vertical memberII at its lower end may have a scoop I2 secured thereto for scooping upVarious materials or substances. This scoop I2 may be detached and aplatform I3 may be secured to the upper end of upright II for holdingsubstances to be weighed. .For lling the scoop I have provided an arm I4riveted to the lever 9 and extending through an opening in the upright 6to a position above the handle '1, for holding the scale mechanism in aninoperative position.

For weighing or counterbalancing a load placed in scoop I2 or on theplatform I3 I have provided Ia pair of springs I5 and IS. One end ofspring I5 is permanently secured to the inwardly extending arm I1attached to vertical member II and the other end is adjustably securedto an inwardly extending arm I8 attached to the vertical member 6.Spring I5 is for low weight range. One end of spring It is adjustablysecured to `arm I8 while the other end is fastened to a pin I9. In orderto increase the capacity of the scales the pin I9 is inserted in theopening I9 in the lug 2G, on pointer or indicating lever 2I, which inturn is riveted to lever I. Before inserting pin I9 in the lug 20, guardarm 22, which is rockably mounted at 22 on pointer or indicating lever2l, and normally held away from the lever 2| by the action of spring 23,must be depressed in order to insert the pin IS. In this way a differentportion of the dial or chart will come in View along the in Fig. 4. Theguard 25, as shown in Fig. 4, is in normal position and permits theright side of the dial to be read along the indicator. By inserting pinI9 in lug 2i), when using both springs I5 and I6, to increase theweighing range o1" the scale, the guard 25 is moved toward theindicating finger 24, bringing the left side of the dial or chart inview along the edge of the indicator, The left upper edge of the guard25 is slightly below the upper edge of the indicating linger 24 whenboth springs are used for weighing.

The dial frame 26, is mounted on vertical member 6, so that theindicating linger 24 will travel along the periphery of the dial orchart 21. This chart 21 is held to the dial frame 26, by screws 28 and29 at the bent over ends. Instead of having the dial on the right sideof the scale as shown on the drawing it may be changed spaceddifferently to take care of the several 1 It is common knowledge thatkinds of mixtures.

the first cup of coffee requires a greater amount of ground coffee thanthe second or succeeding cups, when brewed together. Therefore to takecare of this condition,

other spaces.

To make any number of cups of coifee, the operation is as follows: Placeon the platform or in the scoop enough ground coffee to bring theindicating finger 24 into alignment with the graduation designated bythe numberal indieating the desired number of cups of coffee to bebrewed.

Below the rows of graduations for coifee, I have shown various rows ofgraduations designated by the name of substances or materials andgraduated into divisions of containers. Practically all receipts forpastries etc. used in the home call for cupfuls and teaspoonfuls ofcertain substances. Therefore to more easily obtain the exact quantityof any substance in a receipt in containerfuls without changing theamount into lbs. and oz. I provide on the dial or chart 21 various rowsof graduations indicating cups, teaspoons, and tablespoons.

The operation is as follows to measure any number of cups of asubstance. Place enough of that substance on the platform or in thescoop to bring the indicating finger 24 into alignment with thegraduation designated by the numeral indicating the desired number ofcups in the particular row of graduations allotted to the substancebeing weighed.

While I have shown the chart 2l, as applied to a spring weighing device,it is to be understood that the same features apply to beam scales. Andmay also show weight in pounds and fractions thereof.

It is obvious that the weighing device may take a variety of vothershapes or forms and various arrangements of graduations on the dial maybe made without departing from the essential features thereof. ThereforI do not desire to be limited to the particular form or arrangementshown herein, but contemplate all modifications and changes thereinWithin the terms of the appended claims.

Having thus described my invention, I claim:

l. In a weighing device comprising a frame, a chart having weightgraduations mounted on said frame, a scoop load levers pivoted to saidframe and to said scoop, and providing a parallel linkage there between,a lever holding arm secured to one of said load levers and adapted to beheld in a fixed position relative to said frame to render the weighingmechanism inoperative during a scooping operation, loadcounter-balancing means carried by said frame and I have made the firstspace from zero to one in each row longer than the,

resisting movement of said scoop and load levers' relative to saidframe, and an indicator pivoted to said frame and movable relative tothe said chart to indicate the weight of material in said scoop.

2. In a weighing device comprising a stationary frame provided with asupport, a movable frame provided with a platform, a chart mounted onthe stationary frame having several rows of graduations, some of therows being for a light load weighing range and other rows being for aheavy load weighing range, load levers pivoted on said frames, a pair ofsprings adjustably secured at their upper end to the stationary frame,the lower end of one spring being fastened to the movable frame, thelower end of the other spring being detachably connected to one of theload levers, and an indicator pivoted on the stationary frame andmovable relative to said chart, to indicate light load graduations whenonly one of said springs is under tension and to indicate the heavy loadgraduation when both of said springs are under tension.

3. In a spring scale adapted for weighing light and heavy loads, a charthaving light and heavy load calibrations, an indicator cooperating witheither set of calibrations, means for adjusting the spring resistancefor light and heavy loads, and means operated automatically in responseto such adjustment to select a portion of said indicator and thereby thecalibration which is to be used with said indicator.
